Cy3 F-Luc mRNAs have been designed to produce high expression level of Firefly Luciferase protein.
OZB mRNAs are produced by in vitro transcription. mRNAs are stabilized at the 5’ end by modified nucleotides capping (Cap1) and contain a poly(A) tail at the 3’ end.
Sequences have been optimized to yield improved stability and performance. F-Luc mRNA #MRNA16 does not bear any additional nucleotide modifications while #MRNA12 is modified with 5-methoxyuridine (5moU), #MRNA24 is modified with N1-methyl-pseudouridine (N1-mψ) to reduce innate immune response. #MRNA16B or 12B or 24B are labelled with Cy3 by replacing 15 % of UTP by UTP-Cy3.

Fluorescent F-Luc MRNAs can be traced thanks to their labelling with either the Cyanine3 (Cy3) orange fluorescent dye.
F-Luc mRNAs can be used as control of transfection efficiency. F-Luc mRNAs resemble fully matured mRNAs with 5’cap1 structure and 3’ polyA tail, therefore ready to be translated by the ribosome. mRNA transfection provides several advantages over plasmid DNA (pDNA) delivery. It does not require nuclear uptake for being expressed since translation of mRNA occurs directly into cytoplasm. Indeed, nuclear delivery (transport through nuclear membrane) is one the principal barriers for transfecting slow or non-dividing cells and consequently, mRNA transfection is particularly attractive for such purpose.
This approach presents also the advantage of being non-integrative which is particularly appealing for stem cells, regenerative medicine or vaccine fields. Contrary to pDNA, mRNA cannot lead to genetic insertion causing mutations. Moreover, the protein expression from the mRNA is promoter-independent and faster than with DNA.
For transfection we recommend RmesFect™ (#RM21000) and RmesFect™ Stem (#RS31000).
